|---|---|---|---|---|---|
| Group | The elements in a vertical column of the periodic table.
🗑
|
||||
| Metal | An element that has luster, conducts heat and electricity and usually bends without breaking.
🗑
|
||||
| Metalloid | An element with some physical and chemical properties of metals and other properties of nonmetals.
🗑
|
||||
| Nonmetal | An element that is in general does not conduct electricity, is a poor conductor of heat, and is brittle when solid. Many are gases at room temperature.
🗑
|
||||
| Period | A horizontal row in the periodic table.
🗑
|
||||
| Periodicity | The tendency to recur at regular intervals.
🗑
|
||||
| Semiconductor | An element that does not conduct electricity as well as a metal, but that does conduct slightly better than a nonmetal.
🗑
|
||||
| Transition Element | Any of the elements in Groups 3 through 12 of the periodic table, all of which are metals.
🗑
|
||||
| Actinides | Inner transition metals; radioactive- none beyond Uranium occur in nature.
🗑

| Halogens | Group 17; active nonmetals- never exist alone in nature, tend to gain one more electron (-1 charge)
🗑
|
||||
| Inner Transition Metals | Lanthanides and actinides; complex and ever changing atomic structure, changing oxidation states.
🗑
|
||||
| Lanthanides | "Rare earth metals"; rarely found on earth.
🗑
|
||||
| Metalloids | Can be semi-conductors; have properties of metals and nonmetals.
🗑
|
||||
| Metals | Strong; durable; abundant; lustrous; high melting point (MP).
🗑
|
||||
| Noble Gasses | Group 18; inert, have a full octet of electrons.
🗑
